Background: Association between body mass indexes (BMI)
and blood pressure have been observed, but remains poorly
understood. BMI is shown to be a measure of overweight
status and is applicable to all populations. In this crosssectional
study we have examined the relationship between the
BMI and blood pressure in school age children.
Methods: This study comprised of 486 boys and 463 girls at
aged from 7 to 14-yrs, We examined the age-adjusted relationship
between systolic (SBP) and diastolic (DBP) blood pressures
and BMI in three age groups of 7, 11 and 14-yrs. BMI
was calculated by dividing the body weight in kg by the
square of height in meters (m). At first multiple regression
analyses were separately used for SBP and DBP to establish
their association with BMI, age, gender and height. The analysestest
was then repeated by replacing BMI by adjusted BM!.
Result: SBP and DBP were positively and significantly related
to BMI (P(LESS THAN)O.Ol). According to multivariate regression
analysis, SBP and DPB showed significant associations with
age and weight with respective relation coefficient of 0.569
and 0.469 for BMI, SBP and DBP.
Conclusion: The results of this study showed that BMI was
highly associated and linearly related with both systolic and
diastolic blood pressures in Iranian school-age children.
